Abstract
There are two causes of latency in mobile handover: the move detection latency and registration latency. This delay is inherent in the round-trip incurred by Mobile IP as the registration request is sent to the home agent and the response sent back to the foreign agent. Throughout the time between Mobile Node (MN) leaving the old foreign network (oFN) and Home Agent (HA) receiving the MN registration message, HA does not know MN's latest Care of Address (CoA), and therefore it still forwards the packets destined for MN to the old foreign network. These packets will be discarded and lost. This paper present an improved link layer mechanism with Location information Provider. Global position systems GPS used to assist FMIPv6 for fast handovers and reduced packet loss during handover. We introduce a new link layer combined with Location information Provider signalling in this algorithm accordingly. Further, we report the implementation details performed through simulations
